Loading some 223 for my ar started with some lake city and picked up some Hornady brass I thought it was the military brass with a tight priming hole but the factory Hornady brass seemed to do the same
I'm using the rcbs universal hand primer it works great for large rifle primers but not for small rifle primers
Has anybody used any other brands with better results?
I hope
Your Infromation will be appreciated
Thanks

Lake City brass, if is not new, unfired brass, will have crimped primers, and those crimps don't come out completely with the primer. You have to cut the old crimp out. Some commercial brass also has crimped pockets. Some primers, like TulAmmo and Wolf are also a little fatter than others. If you just need to remove crimps, there have been recent posts on the tools and methods for doing it that you can search for. If you are using the slightly fat primers, though, the solution is likely going to be to use a primer pocket reamer or a a primer pocket swaging tool to loosen the pockets a little.

I would also guess that your problem is the crimped primer pocket. There is 2 ways to get rid of it, swedge it out or ream it out. I much prefer to swedge them out. RCBS makes a die to do it with on your press or if you want to spend the bucks Dillon sells a tool to do it that is really great. You can also pick up a pocket reamer that you just need to twist into the primer pockets. With these you have to be careful not to ream them out to much and get over sized primer pockets and loose primers.

Look at the primer pocket and see if it has a "ring" around the edge of the pocket, if it does that is the crimp, it can cause the primer to be hard to seat.

If you take your chamfer deburr tool and use the chamfer end you can cut a small radius at the lip of the primer pocket, you just need to remove a small amount of metal not the whole "ring", just radius the edge, the force required to seat the primer to the bottom of the pocket will be reduced.

+ 1 on the lee hand primer. If you have Military crimps in your brass,as far as i know from expirence-You will not get a primer to seat no matter what you do, It just will not fit period. Hand press or bench press

sounds like you need to swage your primer pockets. As for hand primers, I own the rcbs and Hornady hand primers. Both occasionally flip primers. The RCBS has a bit more "leverage" for seating primers as the lever hinges on the bottom of the handle where the hornady hinges on the top. The RCBS feels more nature in my grip. However I have never crushed a primer by seating it too hard in the hornady. It has happened with the rcbs though rarely.

I use the RCBS primer pocket reamer on military brass. I also use the Redding debur/chamfer tool and Redding primer pocket tool to clean up the pockets. Some brass will be tight even though it has no crimp.

Sorry, thats my fault I was referring to info on hand primming tools
I was having problems with the rcbs universal hand primer.
I have tried it on lake city brass with crimps removed not sure if they where swaged, So I thought it would do better with once fired commercial hornady brass but NOT.
Thanks for all the input

I've use the RCBS hand primer tool on thousands of .223 cases (small primer) and it has worked fine for me. Like mentioned earlier, are you swapping out the large primer ram and plastic piece for the small primer ram and plastic piece?
